How a Vuln in Dealer Software Could've Unlocked Your Car
Reveals critical API authorization vulnerabilities in automotive dealer management systems that allowed national admin account creation and remote vehicle control.
Summary
Centralized Dealer Management Platforms
Automotive dealerships across the United States rely on centralized software platforms to manage inventory, service appointments, customer records, and connected vehicle features.
Discovering Broken Object Level Authorization Flaws
Eaton Zveare and R Piyush identified fundamental access control vulnerabilities in a leading automaker's dealer platform APIs. Unauthenticated parameter tampering allowed researchers to elevate privileges and create national administrative accounts.
Remote Vehicle Telematics Compromise
With national administrator access, researchers could query customer profiles, retrieve vehicle identification numbers (VINs), and transmit remote commands to lock, unlock, start, and track thousands of customer vehicles nationwide.
Lessons for Connected Automotive Ecosystems
Securing automotive dealer management portals demands strict API authentication, multi-factor authorization on administrative endpoints, and rigorous architectural reviews of third-party vendor platforms.
